I can't speak for the cities. My own research has really focused on the federal level, so I'm not quite sure what the municipalities are defining as their data sets.
It would be logical that the federal government is the owner of quite larger amounts of data than the municipalities. I don't think that would be unusual. There have been some bizarre exercises in counting, if you want to call it that, where I think even at the federal level we've been trying to figure out how many data sets we have.
In my report—and I had provided a link to Marc-Olivier—if we look at various points of time, we can see Treasury Board Secretariat releasing different sets of numbers around the quantity of the data sets that we hold. I can't remember them off the top of my head, but it's up and then it's down, and then it's a little bit up and then it's down again. So I think there is a lot of work to be done around what a data set is. Part of that is figuring out the standards as well. I know that TBS has said that in trying to develop a set of standards, they've worked towards combining some of the data sets and that accounts for some of the fluctuation in the numbers.
